ない影響を及ぼすことがある。Shock waves (called "water hammer") are generated in the electromagnetic valve and the boat, which are propagated by the hydraulic pressure caused by the inertial force of the moving hydraulic fluid. This pressure rises significantly during the short instant after the solenoid valve closes. Adjustment of the usable average pressure for small values of the ratio T 1/T is made difficult by the non-linearity of the change in average pressure as a function of this ratio. Apart from the adjustment difficulties caused by water hammer, this water hammer effect can have undesirable effects on other devices connected to the solenoid valve.

ない制御ユニットによって電磁弁３０を制御する。Referring to FIG. 2, the solenoid valve 30 described above is connected to a pumping device 32 (pressure pumping station), which is schematically illustrated by a piston 34 sliding in a cylinder 35 against the action of a spring 36.

図）内の平均圧力丁のほぼ直線状の調節を可能にする。The diagram in FIG. 4 shows the pressure change between the closing point F and the opening point O of the regulating solenoid valve. The dashed line 40 shows the case of a conventional valve without any element for eliminating the water hammer effect. Immediately after the closing point F, the pressure increases significantly, which decays as a damped wave and stabilizes at a constant pressure PF, which depends on the force to be supplied by the utilization device W33. According to the solenoid valve 30 of the present invention, the water hammer effect is eliminated as shown by the solid line 41 curve. When the pressure I)F is reached when the valve is closed, a shock wave due to the inertia of the moving pressurized liquid enters the chamber 2 against the action of the spring 23 and causes the valve body 3 to enter the chamber 2.
The recoil is almost completely buffered. The moving hydraulic fluid thus becomes progressively stationary at the inlet of the valve 30. Thus, the solenoid valve 30 according to the invention has a ratio T
1/T, the conduit 31 (second
(Fig.) allows an approximately linear adjustment of the average pressure within the range.

In the case of the solenoid valve 30 according to the invention, it is almost straight and the water hammer effect is eliminated. This is shown by the solid straight line 42 connecting the residual pressure PR existing in the pipe 3■ when the valve 30 is permanently opened and the pressure PF corresponding to the continuous closing of the regulating solenoid valve. has been done. As a comparison, the dashed curve 43 shows a large increase in the average pressure due to the water hammer effect for small values of the ratio T 1 /T. That is, in normal valves, there is a nonlinear relationship between the average pressure and the ratio T1/T, so the adjustment by these valves becomes non-tight and complicated, and it is difficult to accurately control the valve. A calibration curve will need to be set. With the valve according to the invention, calibration operations are no longer necessary, since the adjustment follows an approximately linear relationship.
